A new truck service center at Riverhead Ford Lincoln on Route 58, a roughly 7,000-square-foot building, will have eight truck bays for servicing and one extra car bay, said service manager Peter Visconti.

The new bays, which are separate from the existing showroom and service building, will roughly double on-site service capacity for large SUVs, commercial pickups and other trucks.

“I got portable lift that can lift a fire engine if I have to,” said Mr. Visconti, who has worked at Riverhead Ford since 1985.

The shop will be looking for “two or three good mechanics” to help work with the new equipment in the truck service center, he said.

Though the service center has been in the works about eight months, commercial truck manager Bob Forte said few people in town know it’s almost ready to open.

“The way I see it, it’s the best kept secret going,” Mr. Forte said.

The center will hold grand opening celebrations Sept. 14 and 15, featuring show of truck bodies and accessories from manufacturers like Ford, Trius and Dejana. The event will include refreshments and raffle prizes, company officials said.

The center itself will officially open sometime later, after Riverhead Ford Lincoln receives a certificate of occupancy from the town, Mr. Visconti said.
